A range of particulate polyaryletherketone polymers and copolymers, incorporating ether-imide, sulfone, naphthalene, and aliphatic functionalities, along with branching monomers, may be successfully produced by a dispersion polymerisation process, provided that the reaction parameters are optimised. This significantly expands the range of monomers suitable for application in the Friedel Crafts dispersion polymerisation process.
